Abstract: Size effects during phase transformations change the composition of coexisting phases in ternary mixtures. The consequence is a change in the distribution coefficients of the components, which is of interest for microextraction. The concentration dependence of the degree of extraction for separable mixtures (aniline-methylcyclopentane-hexane and water-phenol-toluene) in submicron drops was simulated by the methods of equilibrium chemical thermodynamics. The concentration dependence of the degree of extraction during microextraction for submicron droplets is constructed.

Keywords: phase equilibria, microextraction, thermodynamic modeling, size effect, ternary system.
